I feel like for the some questions (like some of the really hard ones), they want to waste your time on making you handle answer choices A through D, when E is the right answer.
I can't get the data on this because I don't want to spoil the answers for myself, but I'm wondering if this is true or not.
Anyone else feel this way?
the mirroring molecules term is called "chirality" - I got that from watching Breaking Bad :D
